To all whom inn my concern:

Be it known that I, THOMAS C. SEAMAN, of I UNITED STATES PATENT'()FFICE,

THOMAS C. SEAMAN, OF CHICAGO, ILLINOIS.

MACHINE FOR caozmo, CHAMVFERING, 'AND HOWELING BARRELS.

SPECIFICATION forming part of Letters Patent No. 284,245, datedSeptember 4, 1883.

Application filed July 19, 1882. (N model.)

Chicago, county of Cook, and State of Illinois, have invented certainnew and useful Improve ments in Machines for WVorking-Off Kegs andBarrels, of which the following is a full, clear,

and exact description, that will enable others skilled in the art towhich it appertains to construct and operate the same, reference beinghad to the accompanying drawings, and to letters of reference markedthereon, forming a part of this specification.

This invention relates to that class of barrelmachines that are employedin'trimming off the ends of the barrel or package,-chamfering the chine,and howeling and crozing, so that the barrel is all completed and readyto receive the heads and hoops.

Figure 1 is a side elevation of a machine,

partially in section, embodying my improve ments. Fig. 2' is atransverse section in the plane 00 m, Fig. '1, giving an inside faceview-of the cutting mechanism.

Referring to the drawings, A A represent the two side pieces, and A Athe legs, forming the supportingrframe work. The head-blocks B B areadapted to have a longitudinal adjustment and movement on the sidepieces, A

A, for the purpose of bringing these parts nearer to each other, so asto clamp and hold barrels or kegs of different lengths. In practicaloperation, however, the block B is set at the desired point and securedin a stationary position by means of the screw-bolt B and theclamping-plate B The head-block B is retained in position by means ofthe bolt A and the plate B, but is not rigidly secured, and is moved bythe operator pressing on the treadle- I a board 0, as shown by thedotted lines in Fig.

1. This adjustment is accomplished through the'medium of the cord 0,passing over the guide-pulley G which connects the treadleboard and theclamping-disk 03, which forms a rigid part of thehead-block B. When thepressure is relaxed on the treadle-board, the head-block B isautomatically returned to a normal position by means of the spiralspring 0*. The head-block B is provided with a clamping-disk, D,corresponding to the disk 0 These clamping-disks are constructed with alarge opening for the reception of the detachable rings, which aresecured in rela- This machine is adapted to work-ofiboth ends of apackage at the same time. The de scription, therefore, of one end willrefer as well to the opposite end, as both are substan tially alike inconstruction and operation.

The band-pulley a is mounted on the hollow shaft D, which is providedwith the journal bearings a of. This hollow shaft has a rotary but not alongitudinal movement. On the inside of this hollowshaft is placed theshaft D which has both a rotary and a longitudinal movement, rotatingwith but not independent of the inclosing tubular shaft. The shaft D isprovided near the outer end with the longitudinal groove b, into whichfits the screw or pin b, which serves to secure the two shaftsrelatively to each other, so as to compel both shafts to rotate at thesame time, and also toprovide fora longitudinal or endwise adjustment ofthe inner shaft. The outer end of the shaft D has a journal hearing orbOX,.b ,W]1IOh is placed in the enlarged part b of the operating-lever DThelever D is provided near its longitudinal center with the enlargedrectangular part b which is provided with an opening for the receptionof the journal-box b, supporting the end of the inner shaft, D". Thejournal-box b is provided on each side with the lateral projecting pin1), which engages with the slots (2 in the enlarged part b and serves toretain" these parts inproper relation with reference to each other, sothat as the lever D is moved in or p out a correspond ing movementis'imparted to the shaft D". By means of the elongated slot (1 in theedges of the part b the lever D is permitted to have a slight verticaladjustment in order to conform to the change of position when the sameis moved away from or toward the machine proper.

On the inner end of the tubular shaft D is rigidly secured "theannularcutter-plate E, carrying on the inner face thereof thedifferentcutters required. The block d on the cutter-plate is adapted to have alateral adjustment, and is provided with the elongated slot d throughwhich projects the inner square end of the shaft D. The two alternatecorners of the block d are cut away on a bevel, as shown in Fig. 2' ofthe drawings, for the engagement of the inner pivoted ends of the arms dd. The outer ends of these arms are secured to the cutter-plate by meansof the screws f f, allowing the inner pivoted ends to move freely withthe block (1.

To the upper and lower sides of the block d is attached, by means of thescrews Z) I), the angular tool-holding stocks F F. The part of thetool-holder having a bearing on the block (1 is provided with arectangular slot on the upper and lower edge, so that the cuttingmechanism may be adjusted to a greater or less diameter, as may berequired in working off packages of different sizes. The outer ends ofthe tool-holding stocks are recessed for the reception of the cutters,which are secured in position by means of the set-screws d d. The cutterF does the leveling and the companion cutter, F, the howeling, while thecutter F5011 the opposite side does the crozing, and thecompanion'hook-shaped cutter, F clears out the croze, which completesthe package ready for the permanent hoops and heads.

To the inner square end of the shaft D is attached one end of the cordH, which passes up under the guard-sheave h, and is secured at the otherend to one end of the block d by means of thescrew h. One end of acompanion cord, H, is secured to the shaft D 'at W, the opposite endpassing over the guide-sheave If, and being attached to the opposite endof the block (1 by the screw h. Now, by this arrangement, when theoperating-lever is shifted in one direction, one set of cutters isthrown outward toward the edge of the cutter-plate and brought inworking position, while the lever in the opposite direction the positionof the expansible cutters is reversed, the longitudinal movement of theshaft D being simultaneous with that of the operating-lever.

The ring a, is placed in the clamping-disk O and is a duplicate of thering a. (Shown in section in the companion clamping-disk, D.) Anyrequired number of sets of the rings a a may be used, each set being ofa different diameter, in accordance with the diameter of the package tobe worked off. Both ends of this machine are alike, the different partsbeing exact duplicates of the other and adapted to work off both ends ofthe package at the same time, the barrel or keg being held in a stationary position while the crozing mechanism revolves.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The.combination, with the inner end of the shaft D adapted to have botha rotary and a longitudinal movement, of the cutter or face plate E, thelateral moving block (I, provided with the elongated aperture d, thearms cl, having one end pivoted to the face-plate E and the opposite endattached to and moving with the block (1, the tool-holding stocks F F,

attached to and having a lateral adjustment on the block (I, the cords HH, and the guidesheaves h h whereby the cutting mechanism is broughtinto contact with or moved away from the work by an endwise movement ofthe shaft D substantially as and for the purpose described.
